hello I have used PD 150 for a while when I was in school here in vancovuer, and its a great camera, try to use shutter speed and when u want to have some high speed effect try to go down on shutter speed, make sure u do proper white balance and if u want to change tone then take some other color and do white balance on that. if you can manage a diffuser filter or softner filter that will be extra help.And keep Zebra on that will tell you of iris control limits(posted 7476 days ago)
